note 101513 added to function.openssl-pkey-get-public

If you are trying to read a PKCS#1 RSA public key you run into trouble, because openssl wants the public key in X.509 style. The PKCS#1 RSA public key -----BEGIN RSA PUBLIC KEY----- MIIBCgKCAQEAgYxTW5Yj+5QiQtlPMnS9kqQ/HVp+T2KtmvShe68cm8luR7Dampmb [...] cbn6n2FsV91BlEnrAKq65PGJxcwcH5+aJwIDAQAB -----END RSA PUBLIC KEY----- .. is not readable while the X.509 style public key -----BEGIN PUBLIC KEY----- MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAgYxTW5Yj+5QiQtlPMnS9 [..] JwIDAQAB -----END PUBLIC KEY----- is. You can use an easy (and dirty) work around to read the PKCS#1 RSA anyway. The first few bytes of the X.509 style public key contain header information and can shamelessly be copied. In other words: Delete everything after the first 32 bytes from the above X.509 key (starting behind Q8A) and attach your PKCS#1 data, reformat to 64 bytes length and use it with openssl. Please note: The above example only works for 2048 bit length. Like I said - it's kind of dirty - but hey - if you're as desperate as I was.
